Abstract
BACKGROUND/AIM Immune checkpoint inhibitors are highly effective for treating recurrent and metastatic head and neck cancers. However, they require systemic administration and are associated with immune-related adverse events (irAEs). Reducing therapeutic antibody doses to prevent irAEs is challenging. MATERIALS AND METHODS Mouse buccal mucosa squamous cell carcinoma cells (Sq-1979) were transplanted into the backs of mice to induce tumors. The antitumor efficacy and tumor immunohistological environment in tumor-bearing mice were compared after administering a standard dose of programmed death-ligand 1 (PD-L1) antibodies systemically (200 mg/body) or 1/10th of the standard dose (20 mg/body) directly to tumors. Mice received four doses of antibody administered in 3-day intervals. Tumor reduction rates and antitumor efficacies were evaluated 21 days after initiating treatment. CD8+T cell counts and PD-L1, PD-1, perforin, and granzyme B levels; CD25 and Foxp3 expression levels; and tumor Tregs were assessed in the resected subcutaneous tumors. RESULTS The antitumor efficacies in the local low-dose and systemic standard-dose groups were compared with that of the control group. The efficacies of the two treatment groups were similar, and both treatment groups revealed significant antitumor effects compared to the control group. Perforin and granzyme B levels were higher in the local low-dose group (p<0.05). CONCLUSION Local low-dose administration of anti-PD-L1 antibodies exhibits antitumor efficacy similar to systemic standard-dose administration suggesting that local low-dose administration is useful for treating oral squamous cell carcinoma.

Abstract
AIMS/OBJECTIVES The aim of this cross-sectional observational study was to investigate cytogenetic damage to the buccal mucosa in non-smokers and consumers of traditional combustible tobacco products and non-combustible alternatives. METHODS A total of 160 participants were divided into four groups according to the type of product used, including non-smokers, users of conventional combustible tobacco (cigarettes), heated tobacco, and electronic, tobacco-free vapor products (e-cigarettes). Buccal mucosa samples were analyzed using the micronucleus cytome assay to assess cytotoxic and genotoxic damage. RESULTS E-cigarette users showed significantly higher values for all tested parameters in the micronucleus test compared to non-smokers (p < 0.05). Similarly, users of tobacco heating products showed an increase in all parameters (p < 0.05), with the exception of the number of cells with micronuclei. Conventional cigarette smokers showed a notable increase in the number of binucleated cells and cells with karyorrhexis and karyolysis (p ≤ 0.05). When assessing the differences between users of traditional combustible tobacco products and non-combustible alternatives, these did not appear to be significant, except for e-cigarette users, who had significantly more cells with condensed chromatin (p ≤ 0.001), while users of tobacco heating products had more pyknotic cells (p ≤ 0.001). CONCLUSION The results of this study underscore the heightened occurrence of cytotoxic and genotoxic damage in users of both conventional combustible tobacco products and non-combustible alternatives compared to non-smokers, emphasizing the detrimental impact of these products on the oral mucosa.

Abstract
BACKGROUND Polymorphous adenocarcinoma (PAC) is the second-most common malignant tumour of the minor salivary glands. Although PAC predominantly affects the palate, it can also involve the buccal mucosa. This systematic review aims to investigate the literature data about PAC. Furthermore, we report two cases of patients affected by PAC in an infrequently considered anatomical site. METHODS According to PRISMA guidelines, a systematic review search was conducted on PubMed, Scopus, and Web of Science. Observational studies conducted on patients with a histological diagnosis of PAC were selected and analysed. Furthermore, two cases of patients with PAC affecting the buccal mucosa were reported. RESULTS Twenty-nine studies were included, and 143 patients affected by PAC were analysed (62 males, 75 females, and 6 undefined, with a mean age of 57.4 ± 14.5 years). The palate was the most affected site (99/143, 69.2%), followed by the buccal mucosa (12/143, 8.4%). Moreover, we report two cases of patients with PAC affecting the buccal mucosa (one male and one female, with a mean age of 70.5 ± 2.5 years). CONCLUSIONS The present study underscores the importance of considering the buccal mucosa as a possible location of minor salivary gland tumours; although it is a less-considered affliction, it is not uncommon.

Abstract
Oral cancer is a type of malignant neoplasia that develops in the oral cavity or lips and is commonly referred to as squamous cell carcinoma (SCC) because of its histopathology. In this report, we present to you a case of a 35-year-old male patient operated on for moderately differentiated SCC of the lateral border of the tongue and right buccal mucosa with a two-year-old case of trans-femoral amputation. Postoperatively, the patient faced issues with breathing, mouth opening and closing limitations, and painful movements of the neck and right shoulder. An intensive physiotherapy care regimen was designed and consistently implemented for two weeks to tackle the surgical results that were compromising the patient's quality of life. At the two-week evaluation, enhancements in tongue movement, mouth opening, shoulder and cervical joint movement, thoracic mobility, lower limb strength, and gait were seen, confirming the efficacy of the intended therapy. The patient was assessed before and after the rehabilitation using range of motion, manual muscle testing, the Mallampati scale, the numerical pain rating scale, the amputee mobility predictor assessment tool, and the Royapettah scoring system.

Abstract
BACKGROUND Epidermoid and dermoid cysts are benign developmental anomalies that can form anywhere in the body. Despite the rarity of incidence in the head and neck, they can arise at a variety of craniofacial locations. The purpose of this study was to analyze the clinical features of epidermoid and dermoid cysts arising in the craniofacial region with a literature review. METHODS A retrospective study was designed, and clinical features and surgical considerations were investigated from a literature review. Cases of epidermoid cysts in the scalp, temporal area, glabellar area, mouth floor, and buccal mucosa were described. RESULTS Dermoid cysts in more lateral regions of the scalp are rarely associated with intracranial extension. Because temporal dermoid cysts have a high rate of intracranial extension, radiological evaluation of the lesions in the temporal area is imperative. Epidermoid cysts in the glabellar area are usually superficial. Consideration of the surgical approach for an epidermoid cyst of the mouth floor is important. Because epidermoid cysts in the buccal mucosa are extremely rare, differential diagnosis was emphasized. Epidermoid cysts in the scalp, in the temporal intradiploic area, on the glabellar area in the periorbital region, in the mouth floor, and in the buccal mucosa were surgically excised considering the depth and location. Ten cases of epidermoid cysts in the buccal mucosa were retrieved from the literature review. CONCLUSIONS Consideration of the anatomic locations of epidermoid and dermoid cysts in the craniofacial region might help facilitate accurate diagnosis and treatment.

Abstract
OBJECTIVES Patients with urethral stricture due to any type of trauma, hypospadias or gender dysphoria suffer immensely from impaired capacity to urinate and are in need of a new functional urethra. Tissue engineering with decellularization of a donated organ recellularized with cells from the recipient patient has emerged as a promising alternative of advanced therapy medicinal products. The aim of this pilot study was to develop an ovine model of urethral transplantation and to produce an individualized urethra graft to show proof of function in vivo. METHODS Donated urethras from ram abattoir waste were decellularized and further recellularized with autologous buccal mucosa epithelial cells excised from the recipient ram and expanded in vitro. The individualized urethral grafts were implanted by reconstructive surgery in rams replacing 2.5 ± 0.5 cm of the native penile urethra. RESULTS After surgery optimization, three ram had the tissue engineered urethra implanted for one month and two out of three showed a partially regenerated epithelium. CONCLUSIONS Further adjustments of the model are needed to achieve a satisfactory proof-of-concept; however, we interpret these findings as a proof of principle and a possible path to develop a functional tissue engineered urethral graft with de- and recellularization and regeneration in vivo after transplantation.

Abstract
Objectives The aim of our study was to investigate the impact of long-term exposure to heavy metals on the microbiome of the buccal mucosa, to unveil the link between environmental contamination and the oral microbial ecosystem, and to comprehend its potential health implications. Methods Subjects were divided into two groups: the exposure group and the control group. We collected samples of buccal mucosa, soil, and blood, and conducted microbial diversity analysis on both groups of oral samples using 16S rRNA gene sequencing. The concentrations of heavy metals in blood and soil samples were also determined. Additionally, microbial networks were constructed for the purpose of topological analysis. Results Due to long-term exposure to heavy metals, the relative abundance of Rhodococcus, Delftia, Fusobacterium, and Peptostreptococcus increased, while the abundance of Streptococcus, Gemella, Prevotella, Granulicatella, and Porphyromonas decreased. The concentrations of heavy metals in the blood (Pb, Cd, Hg, and Mo) were associated with the growth of Rhodococcus, Delftia, Porphyromonas, and Gemella. In addition, the relative abundances of some pathogenic bacteria, such as Streptococcus anginosus, S. gordonii, and S. mutans, were found to be enriched in the exposure group. Compared to the exposure group network, the control group network had a greater number of nodes, modules, interactive species, and keystone taxa. Module hubs and connectors in the control group converted into peripherals in the exposure group, indicating that keystone taxa changed. Metals in the blood (Pb, Cd, Hg, and Mo) were drivers of the microbial network of the buccal mucosa, which can have adverse effects on the network, thus providing conditions for the occurrence of certain diseases. Conclusion Long-term exposure to multiple metals perturbs normal bacterial communities in the buccal mucosa of residents in contaminated areas. This exposure reduces the complexity and stability of the microbial network and increases the risk of developing various diseases.

Abstract
Introduction Oral carcinoma has been reported at a substantial proportion in patients who never smoke and never drink. However, the proportion may vary by subsite and ethnicity. Objective We aimed to determine the clinicopathological features of buccal squamous cell carcinoma (SCC) in a Japanese population. Methods We retrospectively analyzed the records of patients diagnosed with buccal SCC at our institution from September 2002 to November 2015. We reviewed the gender, age, tumor status, treatment, smoking, alcohol drinking, multiple primary cancers, and prognosis of the patients. The overall and cause-specific survival rates were calculated, and the effects of clinicopathological variables were assessed by univariate analysis. Furthermore, the cause of death was evaluated. Results Among the 63 patients (men: 38; women: 25) included in the present study, 29 (46.0%) never smoked or drank. Women were almost 5 years older than men ( p = 0.014). The number of women in the group who never smoked or drank was disproportionately higher than that of those in the smoker or drinker groups ( p < 0.001). In total, 29 patients (46.0%) had 59 multiple primary cancers, including 26 oral cancers. Surgeries and radiotherapy were performed in 57 (90.5%) and 6 (9.5%) cases, respectively. The 5-year overall survival and disease-specific survival rates were 74.6 and 78.8%, respectively. Conclusion Our study confirms that buccal SCC may develop in older adult Japanese patients, especially in women who have never smoked or drank. These patients could be at risk for second primary malignancy.

Abstract
OBJECTIVES To present a surgical modification for the repair of bulbar urethral strictures containing short, highly obliterative segments and report on long-term objective and patient-reported outcomes. PATIENTS AND METHODS We considered patients undergoing bulbar buccal mucosal graft urethroplasty (BMGU) between July 2016 and December 2019. Eligibility criteria for mucomucosal anastomotic non-transecting augmentation (MANTA) urethroplasty were strictures of ≥2 cm with an obliterative segment of ≤1.5 cm. The stricture is approached ventrally to avoid extensive dissection and mobilisation. Dorsally, the scar is superficially excised and the spongiosum is left intact. Dorsal mucomucosal anastomosis is complemented by ventral onlay graft. Perioperative characteristics were prospectively collected including uroflowmetry data and validated patient-reported outcome measures on voiding, erectile, and continence function. We evaluated functional follow-up, incorporating patient-reported (lower urinary tract symptoms [LUTS] score) and functional success. Recurrence was defined as need of re-treatment. RESULTS Of 641 men treated with anterior BMGU, 54 (8.4%) underwent MANTA urethroplasty. Overall, 26 (48%) and 45 (83%) had a history of dilatation and urethrotomy, respectively, and 14 (26%) were redo cases. Location was bulbar in 38 (70%) and penobulbar in 16 patients (30%), and the mean (SD) graft length was 4.5 (1.4) cm. At a median (interquartile range) follow-up of 41 (27-53) months, the functional success rate was 93%. Whereas the median LUTS score significantly improved from baseline to postoperatively (13 vs 3.5; P < 0.001), there was no change in erectile function (median International Index of Erectile Function - erectile function domain score 27 vs 24) or urinary continence (median International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form sum score 0 vs 0; all P ≥ 0.4). All patients were 'satisfied' (27%) or 'very satisfied' (73%) with the outcome of their operation. CONCLUSION With excellent long-term objective and patient-reported outcomes, MANTA urethroplasty adds to the armamentarium for long bulbar strictures with a short obliterative segment.

Abstract
OBJECTIVE Postoperative pain at buccal mucosal graft (BMG) harvest site hinders the resumption of food intake. We aim to study the effect of inferior-alveolar nerve block plus buccal nerve block (IANB+BNB) on pain scores. METHODS This was a retrospective case-control study performed in a single center from July 2021 to July 2022 (ethics committee approval: T/IM-NF/Urology/23/27). We performed IANB+BNB with a mixture of 5 mL each of 1% lignocaine and 0.25% bupivacaine and 4 mg dexamethasone, in addition to local infiltration of 2% lignocaine and (1:100000) epinephrine combination before harvesting BMG. We retrospectively compared the recorded postoperative pain scores using the visual analog scale (VAS) among patients who received and did not receive IANB+BNB. The time for resumption of pain-free diets and postoperative analgesic requirements was compared. RESULTS The study groups included 20 patients each and were similar in age and graft size. The VAS scores at 0 hours [1.0 (1.25) vs. 2.5 (3.5); P= .043], 6 hours [2.40 (± 0.69) vs. 4.60 (± 0.97); P= .008], 12 hours [2.50 (± 0.97) vs. 4.80 (± 0.92); P= .008], and 24 hours [3.0 (1.25) vs. 4.5 (1.25); P= .002] were better in the intervention arm. However, the pain beyond the second day was similar. The IANB+BNB group resumed solid food quicker, and the cumulative paracetamol dose required was less [8.9 (± 3.03) vs. 16.2 (± 5.06) g; P= .001]. Fewer patients required opioids. CONCLUSION Patients who received IANB+BNB had better pain scores during the first 24 hours following surgery and tolerated solid diet quicker.

Abstract
An engineered bladder construct that mimics the structural and functional characteristics of native bladder is a promising therapeutic option for bladder substitution. We previously showed that pedicled vascularized smooth muscle tissue fabricated by grafting smooth muscle cell (SMC) sheets onto an axial capsule vascular bed had the potential for reliable bladder reconstruction. In this study, we investigated the feasibility of buccal mucosa graft (BMG) integration with the pedicled vascularized smooth muscle tissue to generate a full-layer pedicled vascularized bladder construct. BMG transplanted onto vascularized smooth muscle tissue showed good survival and developed into a pedicled vascularized bladder construct with full-layer structures, appropriate thickness, abundant vascularization, and effective barrier function. Then the full-thickness bladder defects were, respectively, reconstructed by pedicled capsule tissue (pedicled capsule group), nonpedicled vascularized bladder construct (nonpedicled construct group), and pedicled vascularized bladder construct (pedicled construct group). The picrosirius red (PSR) staining and immunohistochemistry results showed minimal fibrosis, maximal smooth muscle proportion, and high vascular density in the pedicled construct group. A continuous mucosal layer was observed only in the pedicled construct group. Moreover, morphological and functional studies revealed better bladder compliance and good ductility in the pedicled construct group. Overall, these results suggested that the BMG could be well integrated with vascularized smooth muscle tissue and generated a pedicled, fully vascularized, and structurally organized bladder construct, which facilitated structural remodeling and functional recovery and could become an alternative to bladder reconstruction.

Abstract
Penile glans amputation is a rare and catastrophic complication of circumcision. Reconstruction of the penile glans was indicated following amputation. Our report discusses a novel technique for reconfiguration of the amputated penile glans of a 5-year-old male admitted 6 months following a complicated circumcision. The parents complained of severe meatal stenosis and penile disfigurement. The penis was 3 cm long. Complete penile degloving was performed. The distal part of the remaining penis was prepared by removing fibrous tissue. Dartos flaps, which had been placed on the dorsal side by the previous surgery center, were divided into two similar parts from the ventral side and opened to both sides at the top of the penis, such as a curtain, and a glanular collar-like structure was obtained by bringing 5 cm × 3 cm buccal mucosa. This structure was covered on the penis as glans, and the freed urethra with the spongiosum was sutured here. The patient was taken to hyperbaric oxygen therapy in the postoperative period. The patient's glans-like cosmetic structure was observed during follow-up, and the patient was urinating normally. This is the first surgical repair technique to use this method in the literature. The use of a dartos flap covered with a buccal mucosal graft is a successful and simple procedure with acceptable cosmetic and functional results for the late reconfigurating a neoglans shape after a glans penis amputation when the penile size is suitable.

Abstract
The present study aimed to determine the risk factors associated with cervical lymph node metastasis (CLNM) in patients with buccal mucosa squamous cell carcinoma (BMSCC). This retrospective study included patients with primary BMSCC who underwent surgery at the Department of Oral and Maxillofacial Surgical Oncology of Tokyo Medical and Dental University (Tokyo, Japan) between January 2008 and December 2017. The following data were collected and analyzed: Sex, age, primary lesion subsite, tumor/node/metastasis stage, clinical growth patterns, tumor differentiation, lymphovascular and perineural invasion, mode of invasion, pathological depth of invasion, extent of tumor invasion, and clinical outcome of patients with BMSCC. Multivariate analysis was performed to identify the possible risk factors for CLNM. A total of 75 patients were included in the present study, among whom 30 (40%) were found to have histological CLNM. Of the 33 patients with buccinator muscle infiltration by the tumor, 24 (72.7%) had CLNM. Multiple logistic regression analysis revealed that buccinator muscle invasion was the most significant predictive risk factor for CLNM in BMSCC. The present study found that tumor invasion of the buccinator muscle was the most significant predictive risk factor for CLNM in BMSCC. Therefore, elective neck dissection should be performed if buccinator muscle invasion is identified in patients with BMSCC.

Abstract
Adenoid cystic carcinoma is a malignant neoplasm primarily of the salivary gland, which can also involve lacrimal glands and other exocrine glands. Adenoid cystic carcinoma rarely presents in the buccal mucosa and young children, and among the major salivary glands, it rarely occurs in the sublingual gland. We are presenting two cases of Grade 1- adenoid cystic carcinoma. One in the buccal mucosa of an eight-year-old boy and another in the sublingual gland of a 50-year-old female patient. The site and age of occurrence can make a huge difference in diagnosis and treatment planning due to the unpredictability of the lesion. Proper diagnosis, treatment planning, and appropriate treatment help improve the lesion's prognosis. Even though such lesions rarely occur, awareness among the Oral and maxillofacial fraternity is very important in providing proper patient care.

Abstract
BACKGROUND/AIM The aim of this study was to investigate the use of spacers and their efficacy in brachytherapy with 198Au grains for buccal mucosa cancer. PATIENTS AND METHODS Sixteen patients with squamous cell carcinoma of the buccal mucosa who were treated with 198Au grain brachytherapy were included. The distance between 198Au grains, distance between 198Au grains and the maxilla or mandible, and the maximum dose/cc to the jawbone (D1cc) with and without a spacer was investigated in three out of 16 patients. RESULTS The median distance between 198Au grains without and with a spacer was 7.4 and 10.7 mm, respectively; this was significantly different. The median distance between 198Au grains and the maxilla without and with a spacer was 10.3 and 18.5 mm, respectively; again this was significantly different. The median distance between 198Au grains and the mandible without and with a spacer was 8.6 and 17.3 mm, respectively; the difference was significant. The D1cc to the maxilla without and with a spacer were 14.9, 68.7, and 51.8 Gy and 7.5, 21.2, and 40.7 Gy in cases 1, 2, and 3, respectively. The D1cc to the mandible without and with a spacer were 27.5, 68.7, and 85.8 Gy and 11.3, 53.6, and 64.9 Gy in cases 1, 2, and 3, respectively. No osteoradionecrosis of the jaw bones was observed in any case. CONCLUSION The spacer enabled maintenance of the distance between 198Au grains, and between 198Au grains and the jawbone. In buccal mucosa cancer, using a spacer in brachytherapy with 198Au grains appears to reduce jawbone complications.

Abstract
Arrhythmogenic cardiomyopathy (ACM) is a heart muscle disease associated with ventricular arrhythmias and a high risk of sudden cardiac death (SCD). Although the disease was described over 40 years ago, its diagnosis is still difficult. Several studies have identified a set of five proteins (plakoglobin, Cx43, Nav1.5, SAP97 and GSK3β), which are consistently re-distributed in myocardial samples from ACM patients. Not all protein shifts are specific to ACM, but their combination has provided us with a molecular signature for the disease, which has greatly aided post-mortem diagnosis of SCD victims. The use of this signature, however, was heretofore restricted in living patients, as the analysis requires a heart sample. Recent studies have shown that buccal cells behave similarly to the heart in terms of protein re-localization. Protein shifts are associated with disease onset, deterioration and favorable response to anti-arrhythmic therapy. Accordingly, buccal cells can be used as a surrogate for the myocardium to aid diagnosis, risk stratification and even monitor response to pharmaceutical interventions. Buccal cells can also be kept in culture, hence providing an ex vivo model from the patient, which can offer insights into the mechanisms of disease pathogenesis, including drug response. This review summarizes how the cheek can aid the heart in the battle against ACM.

Abstract
BACKGROUND The adequate surgical margin for local control of buccal mucosa squamous cell carcinoma (BMSCC) is under debate. This study investigates surgical margins and other factors associated with local recurrence free survival (LRFS) in a large cohort of BMSCC patients. METHODS Multiple factors were evaluated retrospectively in 97 patients with BMSCC. Cox-regression and Kaplan-Meier curves were used for analysis. RESULTS The local recurrence rate was 23%. The tumor-free margin was <5.0 mm in 89% of the patients and the deep margin was significantly more often inadequate. Multivariate analysis associated pT3-classification, former smokers, tumor-free margin status, and postoperative (chemo)radiation (PO(ch)RT) with local recurrence. Re-resections did not improve LRFS in patients with <5.0 mm tumor-free margins. CONCLUSIONS Adequate tumor-free margins are pivotal for LRFS of BMSCC. PO(ch)RT, not re-resection, can improve LRFS in patients with <5.0 mm tumor-free margins.

Abstract
In veterinary clinics, esophageal reconstruction is essential in many clinical situations. In this study, two autografts, the tunica vaginalis (TV) and the buccal mucosa (BM), were proposed to reconstruct a semi-circumferential cervical esophageal defect in dogs. This study aimed to verify whether these two grafts could successfully patch esophageal defects. Twelve male mongrel dogs were divided into two groups. Following cervical esophagoplasty, the defective area was patched with either a TV or a BM graft. Comprehensive clinical, serum biochemical, and histological analyses were performed to evaluate the two grafts. Throughout the study (120 days), the dogs survived the procedure well with minor complications. The lumen of the patched areas was covered with mucosa, with slight scar retraction. Compared with that of the natural esophagus, the average relative luminal diameter was not significantly decreased. Importantly, the measured cortisol and inflammatory marker levels returned to the preoperative levels after 14 days. Although histological examination revealed that both grafts repaired the esophageal defect with complete re-epithelialization, the BM graft showed a histological structure similar to that of the natural esophagus. Both grafts effectively repaired the esophageal defect with minor complications; therefore, both are recommended as promising low-cost clinical alternatives for cervical esophagoplasty in dogs.

One of the rare tumors of the salivary gland is known as basal cell adenoma (BCA). Only a small percentage of salivary gland tumors affect the minor salivary gland of the oral cavity while the majority are found in the parotid gland. We present a rare case of BCA involving the left buccal mucosa of a 45-year-old female. Magnetic resonance imaging (MRI) showed well defined solid mass measuring 1.9 x 1.5 cm in the left buccal space inseparable from the buccinator muscle. The T2-weighted image demonstrates a hyperintense signal post-contrast. Ultrasound-guided fine needle aspiration cytology revealed cellular basaloid neoplasm of uncertain malignant potential. Thereafter excision of the mass was performed through a transoral approach under general anesthesia. Histopathology of the mass showed encapsulated basal cell neoplasm in favor of BCA. The patient was doing well after the surgery and has intact facial nerve and adjacent nerves such as the auriculotemporal nerve and great auricular nerve with no complications then she kept on routine clinic follow-ups, and the surgical site recovered successfully. Therefore, we conclude that MRI and biopsy provide useful information to differentiate between benign adenoma and malignant adenocarcinoma. BCA should be considered in a differential diagnosis of an isolated neck mass. Surgical excision demonstrates an excellent prognosis.

Abstract
This study evaluates the cytomorphometric measures of cells obtained from the buccal mucosa of dental students to assess the fluctuation of the cellular characteristics among relatively normal subjects, with any potential correlations with demographic information, different habits, and hormonal disturbance. This prospective study included 100 dental students with no detectable oral alterations submitted to brush cytology. The smears were fixed with 95% ethyl alcohol and stained with hematoxylin and eosin stain. The stained section was observed under an image analyzer for cytomorphometric analysis. Cytopathological observations were recorded, including inflammation, microbial colonies, micronuclei, keratinization, overlapping, and hemorrhage. Chi-square tests were applied for non-parametric variables. One-way analysis of variance (ANOVA) was used to compare the cytometric parameters to habits and hormonal disturbances. A p-value < 0.05 was considered statistically significant. The results showed close proximity among subjects in the matter of cytomorphometric measures; no significant influence of sex, smoking, alcohol drinking habits, and menstruation was found on cytomorphometric diameters or cytopathological observation, and vice versa, while polycystic ovary syndrome impacted nuclear and nuclear-cytoplasmic ratio (p = 0.003, p = 0.02), respectively. Oral exfoliative cytology combined with cytomorphometric analysis for the studied normal individuals can be helpful in various investigations of oral and systemic diseases.

Abstract
Introduction In developing countries, oral cancer (OC) is estimated to be the third most common malignancy after cancer of the cervix and stomach. The aim of this study was to report the prevalence of OC for 3 years and its association with age, gender, type, and duration of habits along with the site of OC. Materials and Methods This study was conducted in the Department of Oral Medicine and Radiology from January 2019 to December 2021. All the patients were examined after recording their demographic data using a mouth mirror and probe. The diagnosis of OC was arrived based on the clinical features of the lesions. The type and duration of habits and site were recorded in clinical pro forma. The Statistical Package for the Social Sciences (SPSS) software version 21.0 was used for the statistical analysis, the Chi-square test was applied, and the significance level was set at P < 0.05. Results The prevalence of OC was 0.22% in our study. Of 317 cases, the majority of the patients were males (n = 204), and females (n = 113) accounted for a male: female ratio of 2:1. The most common age affected was 51-70 years with a history of tobacco chewing, followed by patients with multiple habits (smokers, tobacco chewers, and alcoholic). The buccal mucosa was the most common site followed by malignancies of multiple sites. Conclusion Regular camps regarding tobacco cessation and counseling should be taken care of by dentists. Male patients aged above 40 years are routinely recommended for dental visits.

Abstract
Oral lichen planus (OLP) is a chronic mucocutaneous, immunological disease that occurs more frequently in the buccal mucosa of middle-aged female patients. OLP's standard treatment is topical or systemic corticosteroids. Due to corticosteroids' numerous potential side effects, there is an effort to find an alternative treatment. One alternative treatment is curcumin. Several studies have investigated the effectiveness and safety of curcumin in OLP patients. In this review, we summarized the literature focusing on the effectiveness and safety of curcumin in OLP patients. Our review of clinical trials revealed that either 6000 mg/day curcumin, 80 mg/day nano-curcumin, or 1% curcumin oral gel 6 times/day offered benefits in the treatment of OLP.

Abstract
Background Carcinoma of buccal mucosa forms a sizeable percentage of the diagnosed oral cavity cancers in India. There is limited data on elective treatment of the contralateral neck for well-lateralized carcinoma with no involved nodes in the contralateral neck. We conducted this study to compare locoregional control in patients treated with unilateral vs. bilateral neck irradiation. Materials and methods 48 patients with carcinoma of buccal mucosa were selected. Patients were divided into unilateral and bilateral arms based on radiation treatment of the ipsilateral or bilateral neck. All patients received adjuvant radiation with Cobalt 60 unit. Patient-specific and follow-up data were collected from records and dosimetric data from treatment planning system (TPS). Chi-square and unpaired t-test was used to compare data between arms and Kaplan Meier plot; Cox regression was used for survival analysis. Results After a median follow-up of 23 months, 15 (31.3%) patients had developed disease recurrence, 8 and 7 in the unilateral and bilateral arms, respectively (p = 0.591). There was no contralateral neck failure during the follow-up period. The 2-year disease-free survival was 68.2% and 72.2% in the unilateral and bilateral arms, respectively. Among risk factors for disease recurrence, depth of invasion (DOI), delay in starting radiation and planning target volume (PTV) coverage were significant contributing factors. Cox multivariate regression suggested DOI and delay in starting radiation to be significant prognostic factors for disease-free survival (DFS). Conclusion Bilateral neck radiation does not provide any advantage over ipsilateral neck radiation for properly selected well lateralized buccal mucosal squamous cell carcinoma. Ipsilateral neck radiation facilitates better sparing of organs at risk.

Abstract
Lymphangiomas are benign hamartomatous malformations, infrequently seen in the oral cavity. They can cause aesthetic issues and functional impairments if not treated in the initial stages, thus necessitating the need to diagnose early. Two presentations were observed: a 35-year-old male with classical frog-egg appearance involving lower buccal mucosa with macrocheilia for two years, which was diagnostic on mucoscopy and histopathology, confirming acquired capillary lymphatic malformation. The second case was of a 12-year-old girl with a gradual appearance of reddish lesions over the tongue and episodic history of bleeding, which was confirmed on mucoscopy, and histopathology is highlighted. Mucoscopy of both the cases showed yellowish-pink lacunae with a hypopyon-like feature and surrounding pale septa. We present two cases of oral lymphangiomas with different presentations and highlight the importance of dermoscopy of oral lesions to bypass invasive techniques such as biopsy.

Abstract
BACKGROUND One-stage buccal mucosa graft urethroplasty (BMGU) is advised for non-obstructing, simple penile strictures due to lichen sclerosus (LS), while a multistage approach is preferred for most complex cases. Our study aims to evaluate long-term treatment outcomes and patient-reported outcomes (PROs) in patients undergoing multistage BMGU for LS-associated penile strictures. METHODS This is a retrospective analysis of prospectively collected data on multistage penile BMGU from 2001. All patients underwent a 2-stage (2St) or 3-stage (3St) BMGU with the final closure of the urethral plate. PROs were collected from a pre-defined questionnaire. RESULTS Twenty patients were successfully treated, while five experienced recurrence. If a first-stage Johanson was only performed, a 3St-BMGU was more likely, and higher treatment success was observed. A time course between the first and last stages shorter than 12 m was an independent predictor of treatment failure. Patients reported high overall satisfaction and urinary flow improvement. Sexual life was not significantly affected, while aesthetic appearance was the most affected dimension. CONCLUSIONS Staged approaches have satisfactory treatment success rates, likely depending on the duration from the first to the last stage. PROs do not differ based on the number of stages performed, and overall satisfaction with the procedure is high.

Abstract
Lipoma is a common tumor of soft tissue with rare occurrence in oral cavity accounting for only 1-4% of benign oral tumours. It may be noticed only during routine dental examinations. Most of them rarely cause pain, resulting in delay to seek treatment. Lipoma of the oral cavity may occur in any region. The buccal mucosa, tongue, and floor of the mouth are among the common locations. A case of large intraoral lipoma occurring in mental region in a 60-year-old female patient is reported. It was treated surgically under local anesthesia, and 6 month follow up showed excellent healing without any recurrence.

Abstract
The surgical advancement of urethral reconstruction is a rapidly moving field. In the last decade, the technique for bulbar urethroplasty has evolved towards less invasive approaches with minimal transection and more tissue sparing in order to increase the patency rate. In this study, we provide a step forward in the augmented non‐transected anastomotic (ANTA) urethroplasty proposed in 2012, with a true mucosa‐sparing modification of the technique. In detail, the bulbar urethral lumen is approached with either a ventral or dorsal urethrotomy. Differently from previous techniques, the native urethral mucosa is neither transected nor resected but is reconstructed with a direct mucosa‐to‐mucosa anastomosis. This allows a complete sparing of communicant vessels that come from the corpus spongiosum to the urethral mucosa. The technique aims to preserve the native vascularity of the urethral mucosa by enlarging the native urethral plate with a direct anastomosis at the level of the stricture, and without the need for resection. In our hands the technique was easy and reproducible, and it carried promising results in the preliminary cohort where it was applied.

Abstract
BACKGROUND Cancer is currently a major public health problem worldwide, with a marked increase of about 70% in the number of expected diagnosed cases over the next two decades. The amount of tobacco and alcohol consumed is calculated based on the subjective information provided by the user. Tobacco exposure can be assessed using the Fagerström Test for Cigarette Dependence (FTCD) and alcohol consumption by the Alcohol Use Disorder Identification Test (AUDIT). MATERIALS AND METHODS Forty-eight subjects answered the Fagerström, and AUDIT tests and we studied them as likely screening tools for oral cancer and their correlation with the expression of CYP1A1, GSTM1, GSTP1, and GSTT1 genes by the RT-qPCR method. RESULTS There were significant differences in the AUDIT score and CYP1A1 expression between cancer and control groups. Participants in advanced stages, whether due to tumor size or regional metastasis, showed significant differences in the duration of tobacco use, FTCD, AUDIT score, and CYP1A1 expression when compared to patients in early stages. Among subjects without cancer, we found a significant correlation between participant age and GSTP1 expression. Furthermore, the expression of GSTP1 was significantly correlated with the number of cigarettes smoked per day, duration of tobacco use, and FTCD. CONCLUSIONS Questionnaires designed to evaluate the degree of tobacco and alcohol exposure and dependence combined with gene expression tests can be useful to assess the risk of developing oral cancer. Furthermore, raising the awareness of individuals regarding their degree of dependence and encouraging them to participate in cessation programs are important educational measures for the prevention of tobacco-related malignancies.

Abstract
Electrospun fiber mats loaded with therapeutics have gained considerable attention as a versatile tool in the biomedical field. While these bandages are largely based on fast-dissolving polymers to release the cargo, stimuli-responsive fiber mats have the advantages of providing a timely and spatially controlled drug delivery platform, which can be refilled and reused several times. These benefits make electrospun fiber patches original platforms for painless and convenient on-demand hormone release. Because of the high need of more convenient and non-invasive methods for delivering insulin, a hormone that is currently used to treat hundred million people with diabetes worldwide, we have investigated the tremendous potential of reduced graphene oxide modified poly(acrylic acid) based fiber mats as an original platform for buccal and corneal insulin delivery on-demand. The PAA@rGO hydrogel-like fibers rendered water-insoluble by incorporating β-cyclodextrin, followed by thermal cross-linking, which showed adequate tensile strength along with high adsorption capacity of insulin at pH 7 and good recyclability. The fiber mats maintained good fibrous morphology and high loading efficiency even after five loading-release cycles. The mucoadhesive nature of the fibers allowed their application for insulin delivery via the eye cornea and the buccal mouth lining, as evidenced in ex vivo studies. Insulin loaded PAA@rGO hydrogel-like fibers showed an insulin flux via buccal lining of pigs of 16.6 ± 2.9 μg cm-2 h-1 and 24.3 ± 3.1 μg cm-2 h-1 for porcine cornea. Testing on healthy adult volunteers confirmed the excellent, mucoadhesive nature of the bandage, with three out of six volunteers feeling completely comfortable (note 8.3) while wearing the patches in the buccal cavity.

Abstract
The major requirement for a dosage form to be successful is its ability to penetrate the site of application and the bioavailability of the drug released from the dosage form. The buccal drug delivery is an influential route to deliver the drug into the body. Here, in this context, various novel approaches that include lipoidal carriers like ethosomes, transferosomes, niosomes etc. and electrospun nanofibers are discussed, with respect to buccal drug delivery. These carriers can be easily incorporated into buccal dosage forms like patches and gels that are responsible for increased permeation across the buccal epithelium. The in vivo methods of evaluation on animal models are conscribed here. The novel biocarriers of lipoidal and non-lipoidal nature can be utilized by loading the drug into them, which are helpful in preventing drug degradation and other drawbacks as compared to conventional formulations. The globally patented buccal formulations give us a wide context in literature about the patents filed and granted in the recent years. When it comes to patient compliance, age is an issue, which is also solved by the buccal route. The pediatric buccal formulations are researched for the customization to be delivered to children. Diseases like mouth ulcers, oral cancer, Parkinson's disease, aphthous stomatitis etc. have been successfully treated through the buccal route, which infers that the buccal drug delivery system is an effective and emerging area for formulation and development in the field of pharmaceutics.

Abstract
OBJECTIVE This article describes a rare case of oral diverticulum. BACKGROUND Diverticulum represents a sac-like protrusion of the gastrointestinal tract, commonly arising in the colon wall of elder individuals. Zenker's diverticulum can also occur in the pharyngeal mucosa. However, oral diverticulum appears rare. MATERIAL AND METHOD The patient was an 88-year-old man with dementia living in a geriatric facility. A dental hygienist incidentally identified a small pouch containing stagnant food residue in the left buccal mucosa during oral hygiene procedures. RESULTS The small pouch with stagnant food residue was identified as a diverticulum. CONCLUSION Diverticula may be identified from the stagnation of food residue. Dental specialists who practice oral hygiene should be aware of diverticula as a differential diagnosis.

Abstract
The ability of sodium caprylate and l-menthol to fluidize phospholipid bilayers composed of lipids simulating the buccal epithelium was investigated using electron spin resonance (ESR) to evaluate the action of these agents as permeation enhancers. 5-Doxyl stearic acid (5-DSA) and 16-doxyl stearic acid (16-DSA) were used as spin labels to identify alterations in membrane fluidity near the polar head groups or inner acyl regions of the lipid bilayer, respectively. The molecular motion of both 5-DSA and 16-DSA showed increased disorder near the polar and inner hydrophobic regions of the bilayer in the presence of sodium caprylate suggesting fluidization in both the regions, which contributes to its permeation enhancing effects. L-menthol decreased the order parameter for 16-DSA, showing membrane fluidization only in the inner acyl regions of the bilayer, which also corresponded to its weaker permeation enhancing effects. The rapid evaluation of changes in fluidity of the bilayer in the presence of potential permeation enhancers using ESR enables improved selection of effective permeation enhancers and enhancer combinations based on their effect on membrane fluidization.

Abstract
Inverted ductal papilloma (IDP) is one of the least common benign papillary/cystic neoplasms of the salivary duct system, being characterized histologically by florid hyperplasia of duct-type epithelial cells into a cystic lumen near the orifice with occasional endophytic growth of the surface squamous epithelium along the terminus of the affected excretory duct. Given its rarity, the exact etiology of IDP remains to be defined. We herein present the first evidence of oncogenic HRAS mutation in a case of oral IDP. This finding, together with the frequent and specific BRAF mutations in sialadenoma papilliferum reported in the recent literature, supports an active role of the MAP-kinase cascade in the pathogenesis of benign papillary neoplasms of terminal duct origin.

Abstract
INTRODUCTION The recurrent course of the disease stricture is a complex problem for both the patient and the operating surgeon and requires an integrated approach to treatment only in expert centers. PURPOSE OF THE STUDY To assess the effectiveness of methods of surgical treatment of recurrent urethral strictures. MATERIALS AND METHODS At the University Clinic of Urology, Russian National Research Medical University named after N.I. Pirogov, an analysis of the results of surgical treatment of patients with recurrent urethral stricture from 2012 to 2020 was carried out. This work included patients who underwent surgical treatment for recurrent urethral stricture. A total of 120 men were involved in the work. The median length of the stricture was (min-max) - 2 (0.5-16 cm). In 95 (79.1%) patients, stricture of the bulbous urethra, in 15 (12.5%) - in the penile urethra, in 2 (1.7%) patients had panurethral stricture, in 6 (5.0%) - membranous urethra and in 2 (1.7%) - meatus. All patients were divided into two groups: with recurrent urethral stricture after primary DVIU (group I, n=77) and recurrent urethral stricture after primary urethroplasty (group II, n=43). Depending on the method of surgical treatment of recurrent urethral stricture, patients in group I were divided into 4 subgroups. Repeated DVIU + 3 months Autocatheterization - 16 (20.8%) patients; End-to-end urethroplasty - 37 (48.1%) patients; one-stage urethroplasty with a buccal graft or skin graft - 22 (28.6%) patients; multistage urethroplasty or perineostomy - 2 (2.5%) patients. Group II was also divided into 4 subgroups. DVIU - 17 (39.5%) patients; end-to-end urethroplasty - 6 (13.9%) patients; one-stage urethroplasty with a buccal graft or skin graft - 9 (20.9%) patients; multistage urethroplasty - 11 (16.7%) patients. Median Qmax - 4.68 ml/sec. Preoperative cystostomy was observed in 31 (25.8%) patients. RESULTS The median follow-up was 24 months (range 12 to 76 months). Depending on the method of surgical treatment of recurrent urethral stricture, the effectiveness of DVIU according to strict indications was 75.7%. End-to-end urethroplasty showed an efficiency of -88,4%. One-stage augmentation urethroplasty had an efficiency of -77,4%, and multi-stage urethroplasty showed an efficiency of 84.6%. The IPSS value for the observation period 2 years was 2.6+/-0.9 points. The average value of Qmax at the time of observation was 19.4+/-7.1 ml/sec. The effectiveness of the treatment was 82%. During the follow-up period, a relapse was noted in 22 (18%) patients. The overall effectiveness of the treatment of recurrent urethral stricture, taking into account the treatment of recurrent cases of disease recurrence, was 97.5%. CONCLUSIONS Urethroplasty is the treatment of choice for recurrent urethral strictures, which has been shown to be more effective than DVIU. However, the results of urethroplasty for recurrent strictures are worse than for primary strictures.

Abstract
The currently available antifungal therapy for oral candidiasis (OC) has various limitations restricting its clinical use, such as short retention time, suboptimal drug concentration and low patients compliance. These issues could be overcome using micro or nanotechnology. In particular, solid lipid microparticles (SLMs) resulted as a particularly promising penetration enhancer carrier for lipophilic drugs, such as the antifungal miconazole (MCZ). Based on these considerations, cetyl decanoate (here synthesized without the use of metal catalysis) was employed together with 1-hexadecanol to prepare MCZ-loaded SLMs. These resulted in a powder composed of 45–300 µm diameter solid spherical particles, able to load a high amount of MCZ in the amorphous form and characterized by a melting temperature range perfectly compatible with oromucosal administration (35–37 °C). Moreover, when compared to Daktarin® 2% oral gel in ex vivo experiments, SLMs were able to increase up to three-fold MCZ accumulation into the porcine buccal mucosa. The prepared SLMs were then loaded into a buccal gel or a microcomposite mucoadhesive buccal film and evaluated in terms of MCZ permeation and/or accumulation into porcine buccal mucosa by using lower doses than the conventional dosage form. The promising results obtained highlighted an enhancement in terms of MCZ accumulation even at low doses. Furthermore, the prepared buccal film was eligible as stable, reproducible and also highly mucoadhesive. Therefore, the formulated SLMs represent a penetration enhancer vehicle suitable to reduce the dose of lipophilic drugs to be administered to achieve the desired therapeutic effects, as well as being able to be effectively embedded into easily administrable solid or semisolid dosage forms.

Abstract
Surgical repair of complex posterior urethral disruptions remains one of the most challenging problems in urology. The efficacy of using a tissue expander capsule as an induced vascular bed to prefabricate axial vascularized buccal mucosa-lined flaps for tubularized posterior urethral reconstruction in a rabbit model was tested. The experiments were performed in three stages. First, silicone tissue expanders were inserted into the groin to induce vascularized capsule pouch formation. Next, buccal mucosa grafts were transplanted into the newly formed capsular tissue supplied by axial vessels for buccal mucosa-lined flap prefabrication. Then, circumferential posterior urethral defects were created and repaired with the buccal mucosa graft (Group 1), the capsule flap (Group 2), and the prefabricated capsule buccal mucosa composite flap (Group 3). After surgery, notable contracture of the tubularized buccal mucosa graft was observed in the neourethra, and none of the rabbits in Group 1 maintained a wide urethral caliber. In Group 2, the retrieved neourethra showed little evidence of epithelial lining during the study period, and the lumen caliber was narrowed at the 3-month evaluation. In Group 3, the buccal mucosa formed the lining in the neourethra and maintained a wide urethral caliber for 3 months. The capsule may serve as an induced vascular bed for buccal mucosa-lined flap prefabrication. The prefabricated buccal mucosa-lined flap may serve as a neourethra flap for posterior urethral replacement.

Abstract
A profound characteristic of field cancerization is alterations in chromatin packing. This study aimed to quantify these alterations using electron microscopy image analysis of buccal mucosa cells of laryngeal, esophageal, and lung cancer patients. Analysis was done on normal-appearing mucosa, believed to be within the cancerization field, and not tumor itself. Large-scale electron microscopy (nanotomy) images were acquired of cancer patients and controls. Within the nuclei, the chromatin packing of euchromatin and heterochromatin was characterized. Furthermore, the chromatin organization was quantified through chromatin packing density scaling. A significant difference was found between the cancer and control groups in the chromatin packing density scaling parameter for length scales below the optical diffraction limit (200 nm) in both the euchromatin (p = 0.002) and the heterochromatin (p = 0.006). The chromatin packing scaling analysis also indicated that the chromatin organization of cancer patients deviated significantly from the control group. They might allow for novel strategies for cancer risk stratification and diagnosis with high sensitivity. This could aid clinicians in personalizing screening strategies for high-risk patients and follow-up strategies for treated cancer patients.

Abstract
INTRODUCTION A thick peri-implant mucosa is of importance to prevent recession, color alterations, bone remodeling and promote "creeping attachment." A volume stable porcine cross-linked collagen matrix has been recently introduced for soft tissue regeneration and volume maintenance. The aim of this study was to investigate peri-implant soft tissue healing and stability on 40 consecutive patients treated with buccal pedicle flap combined with the use of the collagen matrix. CASE SERIES The buccal pedicle flap combined with a volume stable collagen matrix was executed at second stage surgery. The average initial mucosa thickness was 1.32 mm whereas the average band of keratinized mucosa was 1.65 mm and the height 1.3 mm. Four months after surgical procedure and before delivering the final restoration, the peri-implant soft tissue measurements were significantly increased: the average band of keratinized mucosa was 5.10 mm, the mucosa thickness was 3.27 mm, and the mucosa height was 3.32 mm. After 2 years of follow-up, the superimposition of 3D models described an overall volumetric stability of the augmented mucosa with no signs of soft tissue collapse. CONCLUSION The proposed modified buccal pedicle flap was demonstrated to perform well in terms of decreased morbidity, maintenance of blood supply, stabilization of the pedicle, superior haemostasis, and speed of treatment. No significant variations of the keratinized tissue were registered when the buccal pedicle flap was executed in conjunction with the collagen matrix that however provided color match with the surrounding tissue as well as an increased mucosa thickness.

Abstract
INTRODUCTION We report a novel perineal urethrostomy procedure for complete loss of anterior urethral tissue. CASE PRESENTATION A 74-year-old man had complete necrosis of the corpus spongiosum and corpora cavernosa after repeated transurethral surgical procedures. He had been managed with a suprapubic cystostomy tube for 10 years. A perineal urethrostomy was performed, and a posterior wall with an inverted U-shaped perineal skin flap and an anterior wall with a buccal mucosal graft were created. Five months later, an internal urethrotomy was required for mild anastomotic stenosis. Thereafter, an indwelling Foley catheter was used for urine drainage at night to prevent restenosis of the neourethra and avoid excessive nocturia due to low capacity of the long-time disused bladder, and the patient became catheter-free during the daytime. CONCLUSION The method presented here is a reasonable option for patients lacking whole anterior urethral tissue.

Abstract
The aim of this study was to compare two different graft techniques, namely saphenous vein (SV) and buccal mucosa (BM) used together with plaque incision for the treatment of Peyronie's disease (PD) in terms of success, safety and patient and partner satisfaction. The study included 41 patients diagnosed with PD and treated with plaque incision and grafting between December 2015 and November 2019. Eighteen patients underwent plaque incision and BM grafting while the remaining 23 patients underwent plaque incision and SV grafting. Pre-operative plaque size, curvature angle, curvature start time and penis length were statistically similar between the SV and BM graft groups. No statistical difference was detected between the BM and SV graft groups in terms of the sixth- and 12th-month mean International Index of Erectile Function scores, Patient Global Impression of Improvement scores, penis lengths and final partner satisfaction rates during the follow-up period. Residual curvature was observed in three (13.1%) patients in the SV graft group and two (11.2%) patients in the BM graft group. With their high success and low side effect rates, both grafting techniques with plaque incision can be safely performed for tunical lengthening, based on the surgeon's experience.

Abstract
OBJECTIVES Female urethral stricture is a rare disease. Urethroplasty with different techniques using grafts or flaps are successful treatment options. The objective of this study was to present our experience with ventral onlay buccal mucosa graft urethroplasty for the treatment of female urethral stricture disease. METHODS Eight female patients treated with ventral onlay buccal mucosa graft urethroplasty were identified retrospectively. Patient evaluation included physical examination, uroflowmetry with postvoid residual urine measurement, videourodynamics and urethrocystoscopy. Stricture was identified by videourethrography and/or urethrocystoscopy. Urodynamic evidence of stricture was considered as a persistent low maximum flow rate of <12 mL/s combined with detrusor pressure at maximum measured flow rate of >20 cmH2 O in the pressure flow study. RESULTS The mean age was 50.5 ± 4.14 years. Stricture etiology was idiopathic (62.5%) or iatrogenic (37.5%). Two patients (25%) had undergone prior urethral dilations before buccal mucosa graft urethroplasty. Mean stricture length was 1.62 ± 0.44 cm. Stricture location was as follows: four distal urethra (50%), two mid-distal (25%) and two mid-urethra (25%). The mean postoperative follow-up period was 16.37 ± 5.75 months, and the during follow-up success rate was 100%. No complication, such as incontinence or vaginal fistula, was noted, except dyspareunia developed in one patient (12.5%). CONCLUSIONS Ventral onlay buccal mucosa graft urethroplasty is a safe and effective treatment option for female urethral stricture. Unnecessary dilation should not be carried out and buccal mucosa graft urethroplasty in expert centers should be recommended to these patients.

Abstract
The targeted local delivery of anticancer therapeutics offers an alternative to systemic chemotherapy for oral cancers not amenable to surgical excision. However, epithelial barrier function can pose a challenge to their passive topical delivery. The charged, deformable liposomes—“iontosomes”—described here are able to overcome the buccal mucosal barrier via a combination of the electrical potential gradient imposed by iontophoresis and their shape-deforming characteristics. Two chemotherapeutic agents with very different physicochemical properties, cisplatin (CDDP) and docetaxel (DTX), were co-encapsulated in cationic iontosomes comprising 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP) and Lipoid-S75. The entrapment of CDDP was improved by formulating it in anionic reverse micelles of dipalmitoyl-sn-glycero-3-phospho-rac-glycerol sodium (DPPG) prior to loading in the iontosomes. Cryo-TEM imaging clearly demonstrated the iontosomes’ electroresponsive shape-deformable properties. The in vitro transport study using porcine mucosa indicated that iontosomes did not enter the mucosa without an external driving force. However, anodal iontophoresis resulted in significant amounts of co-encapsulated CDDP and DTX being deposited in the buccal mucosa; e.g., after current application for 10 min, the deposition of CDDP and DTX was 13.54 ± 1.78 and 10.75 ± 1.75 μg/cm2 cf. 0.20 ± 0.07 and 0.19 ± 0.09 μg/cm2 for the passive controls—i.e., 67.7- and 56.6-fold increases—without any noticeable increase in their transmucosal permeation. Confocal microscopy confirmed that the iontosomes penetrated the mucosa through the intercellular spaces and that the penetration depth could be controlled by varying the duration of current application. Overall, the results suggest that the combination of topical iontophoresis with a suitable nanocarrier system can be used to deliver multiple “physicochemically incompatible” chemotherapeutics selectively to oral cancers while decreasing the extent of systemic absorption and the associated risk of side effects.

Abstract
Background: Recreational use of the betel nut, which is common among the South Asian population, is a known risk factor for developing Head and Neck cancer. As South Asians comprise a significant proportion of the United States population, we seek to determine if those living within the country experience a higher rate of head and neck cancers compared to other races. Methods: Data of patients diagnosed with head & neck cancers from 2010-2016 was collected from the National Cancer Database® and compared to race-matched US census data for each corresponding year to calculate incidence. Pairwise comparisons were performed between the incidence for South Asians versus Whites and South Asians versus Blacks using one sided Chi-square tests. Results: South Asians experienced a significantly higher incidence of buccal mucosa/vestibule cancers when compared to Whites or Blacks for every year between 2010-2016, but a comparatively lower incidence of larynx or oropharynx cancers. Conclusions: South Asians residing within the United States have a higher incidence of buccal mucosa/vestibule cancers, but a lower incidence of more common cancers, such as larynx or oropharynx cancer. This may suggest that the etiology behind the high buccal mucosa/vestibule cancer incidence is due to a social habit, as opposed to an inherent racial susceptibility.

Abstract
AIM Urethral stenosis is one of the serious complications after proximal hypospadias repair. A variety of techniques has been suggested for its correction, such as urethral dilation using bougies, endoscopic incisions and one- or two-staged urethroplasty with buccal mucosa. The aim of our study was to improve results of urethral stenosis correction in children after multiple proximal hypospadias repairs. MATERIALS AND METHODS A total of 24 patients with urethral stenosis after proximal hypospadias repairs underwent treatment in the Department of Uroandrology of the Russian Childrens Clinical Hospital from 2015 to 2019. The age of the patients was from 3-17 years (average - 4.2) with penoscrotal form of hypospadias in 12, scrotal in 8, and perineal in 4 patients. All children previously underwent 2-8 hypospadias repairs. Patients were divided into 2 groups. In group I, 16 patients had urethral stenosis from the glans of the penis to the penoscrotal area, urethral diameter of 3-4 Ch and ventral penile curvature of 45-60o. These patients were treated with a two-staged urethroplasty, similar to Brackas technique. In group II, 8 patients with urethral stenosis in the penile shaft area, urethral diameter of 6 Ch, without penile curvature were included. They underwent to a one-stage urethroplasty with buccal mucosa graft, which was sutured on the dorsolateral aspect of the urethra, with a formation of the age-appropriate urethra (Dorsolateral Inlay). RESULTS All patients in both groups had successful results with flow rate of 8-12 ml/sec. CONCLUSIONS The correction of urethral stenosis in children after proximal hypospadias repairs can be performed using buccal mucosa. In cases of long urethral stenosis, urethral diameter of 3-4 Ch, penile curvature, and scarring of the penile skin, a two-staged urethroplasty is recommended. In patients with stenosis of the penile shaft, urethral diameter of 6 Ch and lack of penile curvature, a one-stage urethroplasty with buccal mucosa fixation on the dorsolateral aspect of the urethra (Dorsolateral Inlay) allows to achieve successful results.

Abstract
OBJECTIVE Inhalational drugs used in treating asthma have several side effects including those on oral tissues. We therefore designed a study to analyze the effects of inhalational drugs on the buccal mucosal cells of the oral cavity. METHODS Smears were obtained from clinically normal buccal mucosa of 20 randomly selected asthmatic patients who had been under inhalational therapy for at least 6 months. The Papanicolaou-stained smears were then analyzed for average nuclear area, average cytoplasmic area, and average nuclear area:cytoplasmic area ratio for each patient, and the values were compared with those of 10 healthy controls. RESULTS A statistically significant decrease in cytoplasmic area (P<0.001) was found in asthmatic patients compared to controls. A significant increase in mean nuclear area:cytoplasmic area ratio (P<0.001) was noted in asthmatic patients when compared to controls. CONCLUSION Prolonged use of inhalational drugs in patients diagnosed with asthma is associated with changes in oral epithelial cells. There is a need to assess whether these are the direct adverse effects of such drugs and whether they have any long-term impact on oral tissues.

Abstract
The worldwide increased use of mobile phone in recent years has raised many questions on whether their use is safe to user who is exposed to electromagnetic radiation. The aim of the review is to find out the effect of mobile phone emitted radiations on buccal mucosal cells. To identify suitable literature, an electronic search was performed using PubMed, Trip database, Cochrane, Google Scholar and EBSCO host database. The search was focused on the effect of mobile phone radiation on buccal cells. Among the literature available in English, the screening of the related titles and abstracts was done, and only those articles were selected for full-text reading that fulfilled the inclusion and exclusion criteria. The initial literature search resulted in 23 articles out of which only 7 articles fulfilled the criteria were included in this systematic review. The Studies showed that mobile phone-emitted radiations have adverse effects on buccal mucosal cells such as the formation of micronuclei and broken egg which was considered as bio-markers of genotoxicity.

Abstract
The buccal mucosa (BM) of vertebrates is a critical mucosal barrier constantly exposed to rich and diverse pathogens from air, water, and food. While mammals are known to contain a mucosal associated lymphoid tissue (MALT) in the buccal cavity which induces B-cells and immunoglobulins (Igs) responses against bacterial pathogens, however, very little is known about the evolutionary roles of buccal MALT in immune defense. Here we developed a bath infection model that rainbow trout experimentally exposed to Flavobacterium columnare (F. columnare), which is well known as a mucosal pathogen. Using this model, we provided the first evidence for the process of bacterial invasion in the fish BM. Moreover, strong pathogen-specific IgT responses and accumulation of IgT+ B-cells were induced in the buccal mucus and BM of infected trout with F. columnare. In contrast, specific IgM responses were for the most part detected in the fish serum. More specifically, we showed that the local proliferation of IgT+ B-cells and production of pathogen-specific IgT within the BM upon bacterial infection. Overall, our findings represent the first demonstration that IgT is the main Ig isotype specialized for buccal immune responses against bacterial infection in a non-tetrapod species.
